Bug Description
lightdm fails to start on several Lenovo thinkpads (X240, X201, X300, T410...) after the latest round of 15.04 beta updates on 20/03/15. The system boots into low graphics mode, but the only working option from this is the console login.
If the laptops are started using upstart from the "advanced" boot options, lightdm starts as normal on all the affected laptops.
All had been working with systemd running 15.04 beta after earlier upgrades from 14.10 before yesterday's updates.
A Thinkpad T430s is still starting lightdm as normal (i.e. with a systemd startup) after the updates.
gdm will start up OK on the affected machines under systemd. The laptops in question have lightdm, gdm and sddm installed with lightdm as the original default.
Can you attach /var/log/ lightdm/ lightdm. log after this occurs? Thanks.
